Description
~179516 1 SUMMA~Y
The invention relates broadly to the connection and removal of a hub to and from a shaft and more particularly to a hub such as found in a clutch, a brake, or a pulley 5and having a bore for connection with the end of a shaft.
Heretofore, hubs with bores having been removed from shaft ends by means of auxiliary tools existing separate and apart from the hub and shaft.
It is an aim of the invention to provide a dual lOperforming apparatus contained within a hub which not only connects and maintains the hub to the shaft but which also provides a feature for removal of the hub from a shaft.
It will not be here attempted to set forth and indicate all of the various aims and advantages incident to the 15invention, but other aims and advantages will be referred to in or else will become apparent from that which follows.
1 The invention will appear more clearly from the following detailed description when taken in connection with the accompanying drawings, showing by way of example a preferred embodiment of the invention idea wherein like 5numerals refer to like parts throughout.
In the drawings forming part of this application:
Figure 1 is a sectional view of a hub of a clutch and an end portion of a shaft in connection with a bore of the hub by means of an apparatus providing a removable connection of the hub to and from the shaft embodying the invention.
1~79516 1 Referring to the drawings in detail, the apparatus ~
for removeable connection of a hub to a shaft includes the cylindrical hub 10 having the tapered axial bore 12 into which the tapered end 14 of the shaft 16 is mounted with 5the addition of the key 18 in the keyway 20. The tapered bore 12 terminates inwardly in the constant axial bore 13.
The end of the shaft is formed with the threaded axial hole 22 which receives the bolt 24 having the head 26 with the truncated under surface 28 and threaded shank portion 29.
lOThe head of the bolt is formed with the conventional recess 30 for engagement of a tool for actuating the bolt for removal or attachment of the shaft. The apparatus works equally well with a straight shaft and bore illustrated by the broken lines X and Xa in Figure 1.
The numeral 32 designates a mounting washer for the bolt head 26 which includes the circular body portion 34 formed with the axial hole 36 for receipt of the threaded shank portion of the bolt. The axial hole 36 terminates inwardly in the axial truncated circular recess 38 which in 20turn terminates in the internal annular shoulder 40. The inner diameter of the shoulder 40 is such that the head of the oolt may be rotated within the same.
Further provided is the bolt containment and cover ring 42 including the annular body 44 having the recess 45 into 25which the annular shoulder of the mounting washer 32 fits.
The ring 42 includes the axial hole 46 through which a tool is inserted for engagement with the recess 30 of the bolt head 26 and actuation of the bolt for engagement or ~179Si~
1 disenga~ement of the hub from the shaft.
The numeral 43 deslgnates a retainer ring anchored in bore 13 by insertion of the ring into annular groove 50 formed in the axial opening 13 of the hub.
The apparatus is formed and assembled as follows:
The plug P is removed from the hub and then the ~ounting washer 32 is positioned in the bore 13 of the hub and against the shoulder 52. The bolt shank 29 is then ex-tended through the hole 36 of the mounting washer, and the 10 containment ring 42 is positioned against the mounting washer 32 and secured thereto by "Locktite" (T.M.) or othPr conventional securing material. The washer 32 and ring 42 are held within the bore 13 by the snap retainer ring 48 snapped into the annular groove 50.
The hub now has the apparat~s self-contained and is now ready to be mounted on the end of the shaft 16 b~
inserting a tool through the snap ring 48, the containment ring 42 and into engagement with the recess 30 of the bolt.
The shaft is ~ow extended into the bore and the threaded 20 shank 29 engaged with the threads of the axial hole 22. The tool is rotated whereby the bolt draws the shaft up -tightly in the bore and in abutment with the fixed containment ring 32 as a stop thereby mounting the hub on the shaft without the use of any external tools.
To remove the hub from the tapered shaft, a tool is inserted through the hole 46 and into the recess 30 of the head of the bolt and turned counterclockwise on a right handed threaded bolt whereby the hub is forced from the tapered shaft. As the bolt is turned to effect removal -1 of the shaft, the head of the bolt initially backs up and contacts the bolt containment ring 42. With further screw-ing of the bolt, the bolt and containment ring 42 cannot move axially due to the ring 42 abutting anchored ring 48 5 whereby the hub is removed from the shaft, the bolt remain-ing with the hub.
